I really love Google and I really love Firefox. I was looking for how to do a javascript function that would activate on a mouseclick, so I start typing "javascript on..." into my google search bar in Firefox, and it comes up with the autocompletion "onclick" automatically. I didn't even have to click the button and enter the search query, I had the answer right there in my pop-down menu. If that's not efficient, I don't know what is. Of course, I could also download that extension that sticks every known javascript function and its documentation on your sidebar, and maybe I will. Anyway, happy surfing the net.
Life is what you make of it.
